I

AZ 7788 is a meter designed to monitor indoor air quality. It allows the simultaneous measurement of carbon dioxide, temperature and humidity.

It has a built-in NDIR sensor that allows for precise measurement of CO2 levels in real time and a high-class Rotronic sensor for measuring humidity. Results are presented on a large LCD display.

Device can work in the mode of measuring current values, minimum / maximum values ​​(MIN / MAX functions). User can set the CO2 alarm threshold after exceeding which the sound signaling will be activated and changing the temperature reading units (ºC or ºF).

Adapted for continuous operation using the control function, through the contact output, external devices (e.g. fans, solenoid valves, etc.) or for routine instantaneous measurements. It has the function of automatic calibration of the CO2 sensor and a two-point calibration of the humidity sensor.

AZ 7788 is powered by a DC 5V 0.5A adapter.

APPLICATION
Meter can be used as the CO2 checker for the air quality index in all workspace, office, hospital, school, station or home. It can be calibrated easily in the fresh air and its back light function could let user operate in the dark area. AZ 7798 is your best choice as the indoor air quality (IAQ) testers.
